Vedclass · Answer

(B) Net primary productivity $(NPP)$ is the rate at which producers store organic matter in their bodies per unit time and area.It is calculated as Gross primary productivity $(GPP)$ minus the energy lost due to respiration $(R)$,expressed as $NPP = GPP - R$.Secondary productivity is defined as the rate of formation of new organic matter by heterotrophs (consumers) per unit time and area.Both statements are scientifically correct,but the Reason does not explain why $NPP$ is defined as $GPP - R$.

Assertion : Net primary productivity is gross primary productivity minus respiration.
Reason : Secondary productivity is produced by heterotrophs.
